我这里有一个最简单的测试用例:
%module test
%{
static char* MyExceptionName = "_test.MyException";
static PyObject* MyException = NULL;
%}
%inline %{
static PyObject* Foo()
{
PyErr_SetNone(MyException);
return NULL;
}
%}
%init
{
MyException = PyErr_NewException(MyExceptionName, NULL, NULL);
}
以下是setup.py脚本:
from distutils.core import setup, Extension
setup(name="test", version="1.0",
ext_modules = [Extension("_test", ["test_wrap.c"])])
当我按照以下方式构建并测试时,我得到了:
swig -python -threads test.i
python_d -c "import test; test.Foo()"
Fatal Python error: PyThreadState_Get: no current thread
我收到的追踪信息是:
python27_d.dll!Py_FatalError(const char * msg=0x000000001e355a00) Line 1677 C
